Variance of a time series fitted to an ARIMA model I think the variance of the fitted values is is: var(demandts.train.arima.fit) which is also different |

Variance of a time series fitted to an ARIMA model So as you see the sigma2 is different from the variance of your x variable, also it is different from the variance of the residuals: var(residuals(demandts.train.arima)). |

How to draw the regression line and the scatterplot between observed and predicted in R If the observed and the predicted were very close to each other they would be on a diagonal line on your plot. So you may just want to add abline(0,1) after your plot above? |

Independence test for values between 0 and 1 Do your observations represent the number of events over the same number of trials? |

Does anyone know how this visualization was made? the language "processing" can do interactive graphics and 3d. There are examples at both processing.org and openprocessing.org. |

R/Bayes: Why is a wildly different prior not affecting the posterior in bayesglm{arm}? Your data has 2000 points. If the data has high precision and large N this is what I would expect. If you sample the data down to just 50 observations, the estimates change more with different priors. |

What's the distribution of these data? +1 Mixture models are useful. Especially if you have data that is generated under two or more different circumstances. |

What's the distribution of these data? @Macro Many 'off the shelf' distributions can handle both skewed and heavy tailed situations. F and Gamma come to mind, along with nearly all 3 and 4 parameter distributions. I just added an answer so the original poster would have an idea about how to quantify the 'goodness of fit', and make numerical comparisons. |
